4.OA.2:

Operations And Algebraic Thinking

Use The Four Operations With Whole Numbers To Solve Problems.

Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1

4.OA.3:

Operations And Algebraic Thinking

Use The Four Operations With Whole Numbers To Solve Problems.

Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

4.NBT.5:

Number And Operations In Base Ten

Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.

Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

4.NBT.6:

Number And Operations In Base Ten

Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.

Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
